Problems solved by technology
During the construction period, many large-scale machinery and construction vehicles use the garage ramp to pass, and the traffic frequency is high and the load is heavy. The strong vibration has a destructive effect on the completed walls on both sides of the ramp, resulting in cracking of the wall.
Most of the existing wall crack repair technologies are chiseled and hung with glass fiber mesh plastering for repair. The stability of the wall structure formed by this type of repair technology is still poor, and the repaired wall will continue to crack under strong vibration. , causing problems such as increased cost and extended construction period caused by repeated repairs

Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0027] Refer to attached Figure 1~2 , a kind of strong vibration ramp masonry wall crack prevention technology of the present invention, this prevention technology comprises the following steps:
[0028] (1) Construction preparation: use colored strips and waste templates to spread on the ground to prevent the ground from being damaged by beating mortar blocks;
[0029] (2) Marking of cracks: Check the length, width, depth, and direction of cracks, and mark the position of crack removal. The range of cracks should be square and straight to facilitate later construction and ensure beautiful construction;
[0030] (3) Base treatment: Cut all plastering s...

Abstract
The invention relates to the technical field of wall crack repairing, and discloses a control technique for cracks in masonry walls on a slope way under strong vibration. The control technique comprises the steps: construction preparations, crack marking, base treatment, steel nail injection, crack surface clearing, crack sealing, opposite tensioning and tightening with steel nails, steel nail pre-embedding, carbon fiber mesh hanging, surface roughing, plastering and putty powder and paint restoration. According to the control technique of the invention, under the combined action of three waysof injecting structural adhesives into the cracks, performing opposite tensioning and tightening with the steel nails and hanging the carbon fiber mesh, the integrity and structural strength of wallbodies are improved; integrated reinforcing treatment is performed on the interior and surface of a cracked masonry to ensure the integrity and structural strength of the cracks; deformation is evenlydistributed on the whole wall surface, and thus, the ability of resisting the deformation together is greatly increased, and the influence of the vibration on wall cracking is greatly reduced; and the control technique prevents cracks from being generated again after crack treatment, effectively guarantees quality and impression, and avoids the problems that the cost is increased, the construction period is extended due to repeated repairing.
Description
technical field [0001] The invention relates to the technical field of repairing cracks in walls, in particular to a crack prevention technology for masonry walls of strong vibration ramps. Background technique [0002] With the rapid development of my country's economy, more and more large-scale commercial complexes appear, especially in economically developed areas. During the construction period, many large-scale machinery and construction vehicles use the garage ramp to pass, and the traffic frequency is high and the load is heavy. The strong vibration has damaged the walls that have been built on both sides of the ramp and caused the walls to crack. Most of the existing wall crack repair technologies are chiseled and hung with glass fiber mesh plastering for repair. The stability of the wall structure formed by this type of repair technology is still poor, and the repaired wall will continue to crack under strong vibration. , resulting in increased cost and extended co...
